cognitive load theory cognitive load theory historical development and relation to other theories
2010Co-Authors: Roxana Moreno, Babette ParkAbstract:The goal of this introductory chapter is to provide a historical review of the assumptions underlying Cognitive Load Theory (CLT) and to place the theory into the broader context of the learning sciences. The chapter focuses on the theoretical developments that guided the research on cognitive load and learning for the past twenty years and is organized in the following way. First, we examine the nature of the cognitive load construct and compare it to similar psychological constructs. Second, we present a historical review of the development of CLT's assumptions in the following four stages: (a) extraneous cognitive load in problem solving, (b) intrinsic cognitive load and the first additivity hypothesis, (c) germane cognitive load and the second additivity hypothesis, and (d) the evolutionary interpretation of CLT. Finally, we conclude the chapter by examining the constructs and assumptions of CLT in relation to other theories in psychology and education. THE COGNITIVE LOAD CONSTRUCT CLT is a psychological theory because it attempts to explain psychological or behavioral phenomena resulting from instruction. Psychological theories are concerned with the possible relationships among psychological constructs or between a psychological construct and an Observable Phenomenon of practical consequence. A psychological construct is an attribute or skill that happens in the human brain. In CLT, the main constructs of interest are cognitive load , hence the name of the theory, and learning . CLT was developed to explain the effects of instructional design on these two constructs.

Study of the Curvature of Liquid Surface surrounding a Rotating Spherical Object in Gravity Free Space
2020Co-Authors: Rajdeep Tah, Sarbajit Mazumdar, Krishna ParidaAbstract:Concept of curvature of liquid surrounding a spherical surface seems obvious in daily life, but based on earthly conditions everywhere. However, our understanding about the concept seems more transparent when we keep the system out of the usual earthly condition i.e. without gravity. Although existence of forces like adhesion and cohesion along liquid surface come to the fore even in the presence of other force like gravitational ones, but without gravity these forces are solely responsible for kind of Observable Phenomenon. Also, we introduced a form of force responsible for providing a form of potential dominating over the gravitational one. The discussion was provided an ingenious approach, by conserving surface energy, it still explains a lot about what can be done more to explore other properties of rotating liquids in free space.

Probing Wigner Rotations for Any Group
Journal of Geometry and Physics, 2018Co-Authors: Blagoje OblakAbstract:Abstract Wigner rotations are transformations that affect spinning particles and cause the Observable Phenomenon of Thomas precession. Here we study these rotations for arbitrary symmetry groups with a semi-direct product structure. In particular we establish a general link between Wigner rotations and Thomas precession by relating the latter to the holonomies of a certain Berry connection on a momentum orbit. Along the way we derive a formula for infinitesimal, Lie-algebraic transformations of one-particle states.
